PUMP-VALVE.

Specification of Letters Patent. Application filed September 5,

To all whom it may concern:

lie it known that I, WILLIAM G. BLACK,

citizen of the United States, residing at New Philadelphia, in thecounty of Tusrarawas and State of Ohio, have invented certain new anduseful Improvements in Pump-Valves, of which the following is aspecification.

This invention is designed to prolong the period of usefulness of pumpvalves, of the puppet or reciprocating type, and to secure a uniformwearing of the surfaces between the valve and its seat to insure a firmseating of the valve and thereby prevent a waste or leak whichmaterially detracts and effectiveness of pumps and is otherwiseobjectionable.

The invention consists of a rotary member intermediate of the valve andits seat and adapted to be intermittently actuated at each stroke of thepump causing the fluid to pass through the valve.

For a full description of the invention andv the merits thereof and alsoto acquire a knowledge of the details for construction and the means foreffecting theresult, reference is to be had to the following description and accompanying drawings,

While the invention may be adapted to different forms and conditions bchanges in the structure and minor detai s without departing from thespirit or essential. features thereof, meut is shown ings, in which:

Figure l is a vertical central section of the valve embodying theinvention. Fig. 2 is a perspective view of the valve seat. Fig. therotary member. Fig. 4 is a detail section.

Corresponding and like parts are referred to in the followin descriptionand indicated in all the views of the drawings by the same referencecharacters.

The valve seat comprises a hub 1, rim 2, and connectin webs or arms 3,the latter being arrange at a right angle to the plane of the seat so asnot to obstruct the free passage of fluid therethrough. The rim 2 isextended and beveled upon its inner side to cooperate with he outerbeveled edge )f the rotary memb r. 'The rotarymember *onsists of a hub4, rim 5, and webs or arms 3. The webs or arms 6 are inclined in the=amc direction with reference to the plane in the accompanying drawis tobe understood that seat, rotary member, valve,

'a bolt 9, or

. member turns thereby of the rotary member so as to receive the impactof the fluid passing through the valve and thereby produce rotation ofsaid member, whereby it constantly changes its position with referenceto the valve seat and valve to insure a the engaging surfaces, to theattainment of the uniform wearing of which is essential objects in view.It the connecting webs or arms 3 and 6 are of such construction as tominimize resistance to the passage of the fluid through the valve andyet at the same time insure a stable and durable construction,particularly when the valve is designed for use in connection with heavyor large pumps employed in water works. The valve 7 consists of a diskof rubber and ,is

y any as a weight or sprmg, a illustrated and placed upon e severalparts, that is, the and the valve are held in place by means of likedevice, said bolt being usual means such weight 8 bein the valve. T

C OSlHg means threaded into having the rotary member, valve, and valveelosingmeans loose thereon, the valve being adapted to reciprocatewhereas the rotary member is confined between the valve seat and ashoulder 10 formed at the base of the still the preferred embodi reducedportion of the bolt.

the hub of the valve seat and v The chief intent of the rotary member isto effect a truing of the valve and valve seat to insure a firm' andsquare seating thereof to prevent any possible leak which. materiallydetracts from the efficiency of any pump. At each throb or impulse ofthe pump causing it to draw fluid through the 9 valve the latter isunseated and the rotary changing its position with reference to thevalve and valve seat and causing new surfacestocome into contact atthenext seating of the valve, with the result that the parts wear evenlyand uniformly and prevent the cutting away of the valve in laces and theconsequent leak and waste 0 energy ascommonly experienced in the use ofreciprocating valves employed in pumps of large ca acity. It is observedthat the fluid has a irect passage through the openings of the valveseat as, well as through the rotary member the slight resistance offeredby the inclination of the webs or arms 6 being of no consequence ascompared with the resultant advantages and in practice not to bereckoned with because the movability of the rotary member enables thesewebs or arms 6 to be pushed aside by the fluid, the latter havin directaction u on the valve arallel wit the axis thereof to insure positlveunseatmg of the valve. The rotary member is automatic in its action andself-truing, both with respect to the valve and the valve seat, hencethe valve may be used until quite or nearly worn throng The valve seat,rotary member, and valve may be constructed of any material and of anysize or form depending upon the particular use of the valve andaccording as said valve is to he used in connection with liquid or fluidof any nature. The character of valve closing means will depend u on therelative position of the valve aecor mg as the same is to close upwardor downward. In the former the weight must be replaced by a spring, bothbeing common and recogn1zed equivalents.

Havin thus described the invention, what is claime as new is: I

1. In a valve of the character specified, the combination of a valveseat, a valve movable toward and from the seat, a member interposedbetween the valve and its seat for trumg same and adapted to have anintermittent rotary movement im arted thereto at each movement of thesai valve, means for holding said member upon the seat, and other meansfor normally seating the valve upon the rotary .truing member.

2. In a valve of the character specified the .combination of a valveseat, a cooperating reci rocating valve, a rotary member interposebetween the valve and the valve seat and adapted to be automaticallturned by the fluid In its passage through t e valve,

and means for holding the rotary member upon the said valve seat.

3. In combination a valve seat having direct openings therethrough, areci rocating valve, a rotary member interpose between the valve seatand valve and having openings therethrough and provided with webs orarms inclined to the plane of the seat to receive the impact of thefluid passing therethrough. the valve whereby sald member isautomatically turned to effect a uniform wear of the valve and the valveseat, and means for holding the rotary member upon the said valve seat.

4. In combination a valve seat comprising hub, rim, and connecting websor arms, the latter'being set at a right angle to the plane of saidvalve seat, a reciprocating valve, and

an automatically actuated rotary member 10- cated between the valve andvalve seat and comprisin a hub, rim, and webs or arms, the latter einginclined to the plane of the rotary member to receive the im act of thefluid in its passage through the va ve.

5. In combination a valve seat having direct openings therethrough andprovided with a projecting rim beveled upon its inner side, areciprocating valve, and an automatically actuated rotary memberinterposed between the valve seat and valve and having webs or armsinclined to the plane of the rotary member to receive the impact of thefluid in its passage through the valve, the rim of the rotary memberbeing beveled to correspond to the beveled rim of the valve seat. t

In testimony whereof I afiix my signature in presence of two witnesses.
